The DBH 9734 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 63.50 mm shaft diameter, 85.55 mm housing diameter and 12.70 mm height make it suitable for equipment where axial space is limited. It is press-fitted into the housing and runs on the shaft with a flexible lip that compensates for minor misalignment. It is a wear part that should be replaced at the first sign of leakage.

This item is a DBH brand radial shaft seal, identified by part number 9734. Its standard dimensions are: shaft diameter 63.50 mm, housing diameter 85.55 mm and height 12.70 mm. The Mx design corresponds to a seal with a single sealing lip and metal case, intended for press fitting into a cylindrical housing. The 9734 designation makes it easy to locate in catalogs and spare parts lists. It is a standard part in the radial shaft seal category, not a special development.

Seals such as the DBH 9734 are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their function is twofold: to prevent oil or grease from escaping the bearing and to block the entry of dust, water or particles. In food, chemical or water treatment plants, this barrier protects the lubrication and extends bearing life. They are also used in older machines where obtaining the original size is difficult and a compatible alternative is sought.

To select a radial shaft seal, check the shaft diameter, housing diameter and height. The shaft must be within tolerance, with no burrs or deep marks on the sealing track; a rough or worn surface accelerates failure. The housing must be clean and free of deformation. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular and tap only on the outer ring with a support tube. Avoid striking the lip or the spring.

If part number 9734 is not available or you need a nearby size, send us the dimensions of the old seal: shaft diameter, outer diameter and height. With that data we look for an equivalent in the same brand or another brand of similar quality. We can also evaluate variants with an additional lip or a different material depending on the fluid and working temperature. The more complete the information, the faster the response.
